RHBA-2014:1470 - Bug Fix Advisory

Topic

Updated ruby packages that fix several bugs and add various enhancements are now
available for Red Hat Enterprise Linux 6.

Description

Ruby is an extensible, interpreted, object-oriented scripting language. It has
features to process text files and to do system management tasks.

The ruby package has been upgraded to upstream version 1.8.7, which provides a
number of bug fixes and enhancements over the previous version. (BZ#830098)

This update also fixes the following bugs:

• The Tracer module introduced with SystemTap probes in a previous release of

the ruby package collided with native Tracer class implemented in Ruby.
Consequently, when using Ruby with debugger or tracer, the following exception
was raised:

/usr/lib/ruby/1.8/tracer.rb:16: Tracer is not a class (TypeError)

With this update, the Tracer module has been renamed to SystemTap, or DTrace
alternatively. To apply this fix, instances of the Tracer.fire method should be
changed to SystemTap.fire or DTrace.fire in previously written Ruby code.
(BZ#784766)

• Prior to this update, ruby failed to start a SSL server in FIPS mode due to

usage of a forbidden MD5 algorithm. With this update, MD5 has been replaced by
SHA256, thus fixing this bug. (BZ#802946)

• Due to changes in OpenSSL configuration options, the ruby package was not

compatible with builds of OpenSSL that have enabled support for Elliptic Curve
Cryptography (ECC) introduced in Red Hat Enterprise Linux 6. Consequently, ruby
failed to build. This update enables ECC support in Ruby, thus fixing the build
problem. (BZ#997886, BZ#1033864)

All ruby users are advised to upgrade to these updated packages, which contain
backported patches to correct these issues.

Solution

Before applying this update, make sure all previously released errata
relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
